找不到网络浏览器：无法找到可运行的浏览器。 Jupyter笔记本

Jupyter-notebook 无法打开网络浏览器。之前用的好好的，后来windows 10提示更新后就开始在Microsoft Edge中打开了。当我尝试将其更改为默认浏览器（chrome）时，它根本无法打开。

我跟着如何在 Windows 上的 Chrome 中打开 Jupyter 笔记本 https://stackoverflow.com/questions/46829761/how-to-open-jupyter-notebook-in-chrome-on-windows尝试将其改回 chrome。

当我尝试跑步时

jupyter notebook

在 cmd 中我得到的是

[I 21:39:08.015 NotebookApp] JupyterLab extension loaded from C:\Users\roy\Anaconda3\lib\site-packages\jupyterlab
[I 21:39:08.015 NotebookApp] JupyterLab application directory is C:\Users\roy\Anaconda3\share\jupyter\lab
[I 21:39:08.015 NotebookApp] Serving notebooks from local directory: C:\Users\roy
[I 21:39:08.015 NotebookApp] The Jupyter Notebook is running at:
[I 21:39:08.015 NotebookApp] http://localhost:8888/?token=d0a958999d7e59da3f097809882e8f40eb5845e3a07cebe8
[I 21:39:08.031 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[W 21:39:08.109 NotebookApp] No web browser found: could not locate runnable browser.

    To access the notebook, open this file in a browser:
        file:///C:/Users/roy/AppData/Roaming/jupyter/runtime/nbserver-1516-open.html
    Or copy and paste one of these URLs:
        http://localhost:8888/?token=d0a958999d7e59da3f097809882e8f40eb5845e3a07cebe8

但是，当我将网址复制并粘贴到网络浏览器中时，它工作正常。

解决了。

我去了 我的用户目录中的 .jupyter 文件夹> 打开 jupyter_notebook_config.py 文件 > 然后编辑这一行：

c.NotebookApp.browser = 'C:\Program Files (x86)\Google\Chrome\Application\chrome.exe '

to:

c.NotebookApp.browser = u'C:/Program Files (x86)/Google/Chrome/Application/chrome.exe %s'

现在效果很好。
